IT infrastructure teams are responsible for managing the physical hardware that
supports the systems, networks, and storage necessary for IT service delivery. This
includes maintaining mainframes, system security, and network switches (network
management), installing and patching hardware, monitoring assets, and configuring,
deploying, or provisioning servers.
IT infrastructure is traditionally housed in an on-premises data center, where IT
infrastructure teams are responsible for power and cooling. However, infrastructure
is increasingly housed in third-party colocation facilities or virtual IT
environments via a cloud provider. In such cases, IT infrastructure teams are
primarily focused on integrating IT assets between cloud-based and on-premises
environments, as well as maintaining the security and integrity of data across those
environments.
